6 Claims.

This invention relates to an improved trap for throwing so-called clay pigeons, and more particularly to novel mechanism for automatically setting such a trap.

The customary traps heretofore in use have been set by hand. This has required much physical effort in order to overcome the force of the strong springs used to throw the pigeons, and has not infrequently changed the aim of trap. Moreover, there isa limit to the speed with which an operator can set a heavy spring trap.

According to vmy present invention, there is provided mechanism for mechanically and automatically setting the trap upon the discharge of each pigeon. Other features, objects and advantages of the present invention will become apparent or be pointed out in the following description of one form of Amechanism illustrating the invention. Reference is made to the accompanying drawings wherein:

Fig. 1 is a sideelevation of one form of trap in accordance with the invention;

Fig. 2 is a plan view looking down at the top ofthe trap shown in Fig. 1;

Fig. 3 is a horizontalsection through the trap, taken on the line 3 3 of Fig. 4;

Fig. 4 is a vertical section through the trap, partly broken away;

Fig. 5 is a detailed section taken on the line 5 5 of Fig; 2;

Fig. 6 is a section taken on the line 3 6 of Fig. 3;

Fig. 7 isa section similar to Fig. 6, but showing the parts in a different operating position; and

Fig. 8 is a section taken on the line 8 8 of Fig. 3.

The trap shown in lthese drawings includes a trunnion I i! carried in a suitable support II and mounting a frame I2 on which the various elements of the mechanism are mounted. It will be understood that the support may include any suitable means for varying the elevation and lateral angle of the trap. The trap includes an arm I3 for throwing the clay pigeon, a rock-shaft I4 to which this arm is secured, a coil spring I5 for returning the arm I3 to its position shown in Fig. 1, and heavy coil springs I6 attached at one end to a crank arm I1 on rock-shaft I and at the other end to a connecting rod I8 which is journalled on a crank I9 mounted in the frame through bearings 2i). A locking pin, 2l normally holds the pigeon throwing arm I3 in trap-set position, and is retractible by means of a hand operated lever 22 which is pivoted on the frame at 23 and connected, as shown at 24, to the locking pin EI. A spring 25, shown in Fig. 4, serves to urge the pin 2l into locking position.

An electric motor 33 is secured to the frame and drives a worm 3l on shaft 32 through a small pulley 33 on the motor shaft, a belt 34, and a large pulley 35 on the shaft 32. The worm 3I is in mesh with a gear 36 secured to a collar 3l journalled on the shaft 38 of the crank I3. As best shown in Figs. 6, '7 and 8, this collar is provided with a pin 39. Secured to the crankshaft 33, for instance bymeans of a pin 'l, is a collar llI which is provided with a stud 42 located in recess 53. The collar il is also provided with a shoulder 44 which engages a notch l5 in a latch arm 45. This arm 66 is pivoted on the frame as shown at Llland is constantly urged toward latching position by a spring d3. Arm 65 has a vertical portion 49 at its outer end, adapted to be struck by arm I3 just after the pigeon has been discharged, when the arm I3 reaches its limit position sho-wn in dotted lines in Figql.

The crankshaft I9 is provided with a cam 5I, shown in Figs. 3 and 4. This camcooperates with a camv follower 52Hmounted on a lever arm 53. Thisk lever arm 53 is pivoted on the frame at 54 and is' connected to a' spring 55 which urges the cam follower against the surface of the cam. The end of the arm 53 extends between the prongs of a forked member 55 which is connected to a switch in box 5l. 'Ihe switch, through leads .58, .serves to start and stop the motor under control of the cam 5I, as will hereinafter be described.r

The operation of the device is as follows: When the parts are in their position shown in Fig. 1 the trap is set. The operator then places a clay pigeon on the left hand end of the pigeon throwing arm I3. Any suitableor known device (not shown) may be employed for holding. the pigeon on the arm I3 during the swinging of this arm. The operator then pushes up on the end of lever 22, thus withdrawing the locking pin 2 I, and permitting the arm I3 to swing forward and discharge the pigeon. As this arm approaches the end of its swing it strikes the upright portion 49 of the arm 46, thus disengaging the notched portion 45 from the flange 44, and permitting the springs I6 to contract. The crank I9 and the collar 4I are thereby rotated in a clockwise direction from their positions shown in Figs. 1 and 6 to their positions shown in Figs. 3 and '7. As the parts thus move from the positions shown in dotted lines to the positions shown in solid lines in Fig. 4, the cam follower 52 runs off the hump on the cam and starts the electric motor 3i?. Meanwhile, arm I3 has been returned, by the action of spring l5, to its locked position as shown in Fig. 1. The motor then turns the collar 31 to move the pin 39 from its position shown in Fig. 6 to its position shown in Fig. 7 where it engages the stud 42. The motor thus picks up speed under no load conditions before the pin 39 engages the stud 42. As the motor continues to operate, the pin 39 causes the collar 42, and through it the crankshaft I9, to rotate in a clockwise direction until the crank I9 passes dead center and the pin 39 reaches approximately the position shown in Fig. 6. At this point two operations occur: (l) the cam follower 52 runs up on the hump of the cam to stop the motor; and (2) the springs I6, which have thus been placed under tension, ment with notch 45 to lock the parts in trap-set position. The trap is now ready to receive the next pigeon.

Through the present construction there is provided a trap which is mechanically and automatically returned to trap-set position, after the operator has sprung the trap to discharge a pigeon. The operator has only to place the pigeon in position, and spring the trap when the man shooting calls pull The present trap permits the use of springs of any desired strength for throwing the pigeons at the high speed and over a long range, all without the need for manually resetting the trap after the discharge of each pigeon. The resetting of the present trap has no tendency to change its aim. I have found that the parts can be designed so that only about two seconds are needed to reset the trap after a pigeon has been discharged. One particular advantage of the present construction is that it permits the use of an electric motor which operates always in one direction, thus avoiding the need for complicated reversing mechanism. Another advantage is that the motor starts under no load, and reaches full power before it begins to stretch the pigeon throwing springs. By stopping the motor just after the crank passes dead center and just before the parts reach trap-set position the device operates smoothly and with minimum wear. Moreover, the device is fully automatic, and can readily be incorporated in existing traps. Y

The terms and expressions which have been employed are used as terms of description and not of limitation, and there is no intention,V in the use of such terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
